BRUCE W. TRAYLOR, OF NEVT YORK, N. Y., ASSIGNOR 'IO TRAYLOR ENGINEERING AND MANUFACTURING 00., A CORPORATION OF DELAWARE.

GEARING.

Application filed November 29, 1912.

To all whom it may concern Be it known that I, Bauer: WV. TRAYLOR, a citizen of the United States, residing at New York, N. Y., have invented certain new and useful Improvements in Gearing, of which the following is a specification.

My present invention relates to gearing for imparting relative reciprocation to rotary members, and particularly to imparting such reciprocation to one of a pair of crushing rolls.

It has for its object to provide mechanism by which, whi e the reciprocation may be effected automatically, yet when desired the automatic mechanismmay be thrown out of action and the roll permitted to run in one position for any desired length of time.

A further object is to provide means by which, when desired the reciprocation may be effected by hand, and a still further object is to provide means by which the roll and its mechanism for producing endwise reciprocation may be adjusted bodily to produce perfect alincment of the rolls.

With these and possibly other objects in view, the invention includes the novel features of construction and arrangement and combination of parts hereinafter described and particularly set forth in the appended claims.

In the accompanying drawing Figure 1 is a sectional view through a crusher. constructed in accordance with my invention, the section to the right of the broken line midway of the figure being in proximity to one roll shaft while the section to the left is in a plane in proximity to the other roll shaft.

ig. 2 is a plan View of the right hand end. portion of Fig. 1. with the cover of the gear case removed; Fig. 3 is a sectional plan, the section being taken on line 3-3 of Fig. 1; and Fig. 4 is a side elevation of the gear box.

In these drawings, the numeral 1 indicates one of the crushing rolls, and 2 its shaft. With this roll is associated another roll, as is customary in this art, between which rolls the material is to be crushed. The rolls are rotated in any suitable manner, as, for instance, by applying power to one roll and rotating the other by frictional contact with the power driven roll, but as the second roll and manner of driving the same forms no part of the present invention, more detailed illustration of the relative relation of the rolls is deemed unnecessary.

Specification of Letters Patent.

Patented Aug. 4:, 1914;. Serial No. 734,147.

My complete mechanism for imparting the longitudinal movement to the roll shaft comprises the following: I provide at one end of the said roll shaft a transverse shaft 3 mounted in suitable bearings in the frame, as indicated at 4:, and this shaft is provided with an eccentric portion 5 fitting in a recess in the block 6, which is carried by the end of the roll shaft in such a manner as to permit the rotation of the roll shaft but not longitudinal movement of the block with relation to the shaft,: the said block being formed in two sections, 6 and 6, which embrace ribs 7 extending circumferentially of the reduced end of said roll shaft. In order to produce automatic reciprocating motion of the roll shaft, the eccentric shaft 3 is rotated through a gear 8 fast thereon, and meshing with a gear 9 which has its hearings in the frame member 4, and this shaft is provided with a worm wheel 12 with which meshes a worm 13 fast on the reduced end of the roll shaft and rotating therewith. It will now be seen that as the roll shaft is rotated, the worm at the end thereof will, through the gearing described. rotate the eccentric shaft 3, and this shaft, working in the forked or recessed lower portion of the block or blocks 6, 6, will give a longitudinal reciprocation to the roll shaft, and consequently the roll, to displace it axiallv in relation to the companion roll. It will be understood by those skilled in the art that this longitudinal movement of one roll is to prevent corrugating or grooving of the faces of the roll, be cause where rolls run without this relative longitudinal movement for a long time. the ore may run more to one point than another, and wear the shells or tires of the rolls more at one point, thus producing annular grooves. For some kinds of work, however, it is desirable to run the rolls for a time without relative endwise movement, then to effect a slight reciprocation of one roll, and thereafter to continue the rotation without reciprocation. In order that this may be accomplished, I provide means for rotating the shaft 3 by hand, as, for instance, by squaring the end of the shaft, as indicated at 3, and providing it with a crank 3 The rotation of the shaft 3, however, could not be effected by hand with the gearing heretofore described in mesh. For the purpose of interrupting the gearing, therefore, I

mount the worm wheel 12 loosely on the shaft 10 and arrange for it to be clutched thereto and unclutched therefrom by a clutch member 14 splined on the shaft, and adapted to be operated by a fork 15 carried by a sliding rod 16 supported in the gear case or frame of the machine. Thus by disconnecting the clutch the train of gearing is interrupted so that the shaft 3 may be rotated by hand, the gear 9 and the shaft 10 rotating idly with it.

In putting a new tire on a roll, owing to a slight difference in the inside diameter 'of the tire, there is a possibility that it may be drawn on farther than or not so far as the old tire, and thus the face of the tire may not be exactly opposite the face of the other roll. To overcome this, provision is made by which a permanent adjustment of the roll and the reciprocating mechanism may be effected. For this purpose 1 form the frame portions 4 in which the shafts 3 and 10 are journaled independent of the main frame of the machine. These bearing portions 4 are adjusted by means of set screws 17 threaded through lugs 18 on the faces of the members 4;, and Working between lugs 19 carried by the lower portion 20 of the gear box. Thus by turning the screws the entire set of gearing and roll shaft may be adjusted to secure proper alinement between the two rolls.

I claim as my invention 1. In combination with a supporting frame and a rotary member journaled therein, mechanism including a train of gearing by which the rotation of the rotary member automatically effects a slow endwise movement, and means adjustably supporting said mechanism from the main frame whereby the roll and with it said automatic mechanism may be bodily adjusted in relation to the main frame.

2. In combination, a main frame, a rotary member journaled therein, a worm carried by said membenbearing members adjustably carried by the main frame, a pair of transverse shafts journaled in said adjustable members, a worm wheel on one of said transverse shafts engaging the worm, and means whereby the rotation of the other shaft effects endwise movement of the rotary member, substantially as described.

3. In combination a main frame having a gear box at one end thereof, a rotary member journaled in the main frame having a shaft extension projecting into the gear box, a worm carried by said shaft extension, bearing plates adjustably mounted on opposite sides of said gear box, a pair of trans verse shafts journaled in said bearing plates, a worm wheel on one of said transverse shafts engaging said worm, gearing between said shafts, means whereby the rotation of the other shaft efiects endwise movement of the rotary member, and means interposed between said bearing plates and the sides of the gear box for effecting lateral adjustment of the bearing plates and the entire mechanism within the gear box, substantially as described.

In testimony whereof, I affix my signature in presence of two witnesses.
